Comment 17 for bug 1545302

Hi folks.
Dariusz fix worked for me.
I reverted my config to failure mode -- while i was connected to the wifi, I did not get an IP address.

Changed the wifi to use wpa-conf (so I had a network to do the upgrade).
Upgraded to the ppa
Changed the wifi back to using wpa-roam
ifdown / ifup -- all good
rebooted -- all good.

here is my network/interfaces:
========================
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

iface eth0 inet dhcp

auto wlan0
allow-hotplug wlan0
iface wlan0 inet manual
  wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf
#iface wlan0 inet dhcp
# wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

iface default inet dhcp
===================

Here is my wpa_supplicant.conf:
===================
update_config=1
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev

network={
        ssid="MySSID"
        psk="MyPSK"
        id_str="home"
}
===================

@Robert: Just checking, but your wpa.conf file is actually named wpa_supplicant.conf -- Yes??
